In this paper, the authors is to discover and implement a method of encoding an audio data from a MIDI audio file format into a special type of Quick Response (QR) code 2D barcode called Color Quick Response (CQR) code which is a 2D barcode that has been extended into a 3D barcode system. The benefit of this research paper is; to show and explore the potential of using CQR code as a medium to encode audio files, which open the possibility to encode audio messages into a 2D barcode.
